Even without capitalism I prefer having been able to read the existing books without an ending over not being able to read any of them. I can get some enjoyment from the journey even without a destination
You don't need Thunderbolt for Displayport alt mode. It's a separate spec that can also be implemented independently. I have a dock that's not Thunderbolt but supports DP alt mode.
Last I heard Cinnamon does not have stable Wayland support yet. One of the reasons Wayland was made is because multi-screen support on the old X11 is an ugly hack. Unlike wayland, it doesn't play well with screens of different resolutions, refresh rates, adaptive sync compatibility or HDR.
No. The Rust code in the kernel is GPLv2 just like the rest of the kernel. The licence of the compiler has nothing to do with that, that's nonsense Rust haters make up.
You can argue against independent projects like the Rust coreutils not using a copyleft license, but that has nothing to do with Rust or the kernel. There are independent C projects without non-copyleft licenses too.
